, This invention relates to the class of devices known as outboard motors, which are used principally for propulsion of row boats and other small craft. An outboard motor is 5 a self-contained apparatus, adapted to' be attached outboard to a boat, usually astern, and which comprises al motor and a depending shaft driven thereby for operating a propeller carried by the foot'of the apparatus.

Among the objects contemplated by this invention are, first, to provide an outboard motor of improved general character and operation; second, to provide a practicable construction embodying provision for discon- IS necting the propeller-operating shaft from the motor or engine at will, so as to permit discontinuing the propulsion of the boat with out the necessity of stopping the motor; third, to provide improved means for circulating 2: water to the water jacket .or cooling system of the engine, and particularly to make pro-V vision for continual pumping of water during the running of the engine, whether the propeller is operating orl not; and, fourth, i to provide improved means in connection with the steering. Further incidental or contributory objects will hereinafter appear.

The invention will be explained by refer.- ence to an'illustrative embodiment thereof shown in the accompanying drawings, it be- Ving understood that the following specic description of the embodiment selected for illustration is not to be taken in a restrictive sense, and that the novel and improved features, constructions, combinations and subcombinations comprising or embraced within the invention are more particularly pointed .out in the claims appended to this description. i" Vln said drawings:

Fig. ll is a section taken on the line 11 11 of Fig. 2 looking in the direction of the l arrows. 1 75 The motor of the illustrative apparatus is represented by a two-cylinder gasoline engine of a well-known type. Certain of its parts may be briefly referred to as follows: In the drawings, the cylinder and crank case as a whole is designated by the numeral 1. Reciprocating in the cylindersI of'the case are the pistons 2 suitably connected by pitmen 3 with the cranks 4 of the crank-shaft 5 (Fig. 3) The crank-shaft which is vertically disposed carries at its upperA end the usual flywheel 6 and starting-wheel 7. In Figs. 1 and 2 the gasoline or fuel tank is indicated at 8, the carburetor at 9, and the exhaust muiier at 10. These parts other than the motor crank- 90 shaft are referred to merely for a general eX- planation of the drawings. Further descrip? tion of the motor is unnecessary since its co1istruction and operation are well known to those skilled in the art. Furthermore, it will be understood that the particular motor shown is merely exemplary and typifies any suitable motor for the purpose. f In the illustrative structure,-the propeller for the boat is arranged as usual at the ma the drawings by the numeral 11.

foot kofthe device and is operated from the motor through a vertically-disposed drive shaft, hereinafter referred to as the propeller-operating shaft, which is designatid in t is otperative'lyconnected at its upper. end with t e motor shaft. 5 through a clutch mechanism hereinafter referred to. At its lower end said shaft 11 is shown connected by the bevel-gears 12 with the shaft 13 of the propeller 14 (Fig. 1*). The case which carries the .said gearsand bearings forthe ropeller shaft and lower end of the shaft 11 is designated by the numeral 15. In this instance a rudder 14a is shown depending from said case in advance of said propeller. Said case 15 carrying the rudder and propeller is lattached to the foot of the tubular post 16, hereinafter for convenience referred'to as the rudder post, although that term does not necessarily imply use of a rudder sincesteering may be accomplished by change of angular osition of t e propeller itself. Supporting sleeves in which the rudder post is rotatably mounted are indicated at 18 and 19. Between the upper supporting sleeve 18 and the motor case lis an interposed clutch casing 20 hereinafter referred to. The said supporting sleeve, motor case and clutch cas- Aing are suitabl secured together as a unitary or rigid struc ure, and the said supporting sleeve 18 may be attached to a boat in a customary, manner. In this instance, the supporting sleeve 18 is shown constructed with a sleeve clamp 21 embracing a transverse supporting bar 22 which is suitably at-v tached to the boat. l For example, the supporting bar 22 with the outboard motor carried thereb may be attached to the sternboard 23 o the boat by ordinary brackets. YOne of suchbrackets is indicated at 24. A

clamng screw by which the bracket is secure to the stem-board is indicated at 25. An arm 26 extending from the bracket is bolted to the lower supporting sleeve 19, the said arm having a series of perfor-ations for adjustable connection. It will be understood that byvirtue of the sleeve clamp 21 and the adjustable connection of the arm 26 with the supporting sleeve 19, the outboard motor. may be mounted with rovision for suitable adjustment of its position in relation to the vertical. r

Referring now to the operative connection between the propeller-operating shaft 11 and the' motor shaft 5, this is provided by a suitable clutch contained'in the clutch casing 20. A, simple and practicable .type of friction clutch is shown adapted to be operated by a clutch-throw lever conveniently associated` erating shaft 11 1s a clutch member 30 in the thrust shoulder and a retaining nut 40. The

on its shaft by any suitable means, such for instance as the keys 31 and the set screw 32.

The keys 31 engaging a longitudinal groove 4 in the shafthold said clutch cone from turn` ing on said shaft, and the set screw holds it from moving longitudinally on its shaft. The clutch cone 30 is shown arran ed with its smaller end up and is ada ted to. e engaged by the downwardly extending bell-shaped interiorly conical portion 33 of a movable clutch member 34. Said movable clutch member 34embodies a sleeve portion which is slidably but non-rotatablyfitted on a sleeve 35. Such slidable and non-rotatable connection may be provided by the keys 36 carried by the sleeve 35 and engaging a longitudinal slot in the sleeve portion of 4the movable clutch member. The sleeve 35 is rigidly affixed on the lower endl of the motor shaft, being in Athis instance screwed thereon at 37. As

the motor shaft always turns in they same direction, and the screw threads at 37 are contrary to the direction ofI rotation, a suiliciently secure connection is provided by the screw. The sleevel, 35' is shown extending slightly beyond the yend of the motor shaft and contains a bushing 38 in which a reduced terminal of the propeller-operatin shaft 11 is fitted. Swivelle'd n the slda leclutch member 34 is a ring orgclutch collar 39, which in this instance is sliown fitted between a.`

ring or clutch collar 39 has diametrically op posite openings en aged by the screw studs 41 carried 'by the yo e arms l42of a 'lyoked or forked lever 43 (Figs. 2 and 3). he openings in the yoke arms for the studs 41 may be short slots to permit the necessary play as 1 the lever is operated. The yoked levem43 is fulcrumed at 44 in the rear side of the clutch case. lThe frontend of said yoked lever 43 is connected by` a linkor parallel links 45 to a clutch-throw or shifting lever 46 which is fulcrumed at 47 and the handle portion 46"L of which extends through a vertical slot or opening in the front of the clutch case to vconvenient position for operation by the person seated in the stern of the boat. The pivot connection between the yoked lever and link is indicated at 48; and the pivot connection between the link and clutch-throw lever is indicated at 49.

In Fig. 2, the V'parts are shown positioned to hold the clutch members separated. Normally, however, the sliding clutch member 34 vis depressed and held in engagement with the clutch/member 30 b the coiled spring 50 which/.surrounds the ower crank s aft bearing and acts on the clutch collar to ress the sliding clutch member 34 downwar against the clutch member 30; Said spring -is shown interposed between the nut 40 and the lower element of an antifriction thrust bearing 5l 13 ne 'I fitted against the bottom of the motor case. Said bearing comprises confronting grooved plates and interposed balls, so that the coiled spring 50 may rotate with the motor shaft. I

, When it is desired to disconnect thepropeller-operating shaft from the motor shaft, the lever 46 is raised to the position shown in Fig. 2, thereby through the link connection 45 raising the forked lever 43 and the clutch collar connected therewith and so lifting .the sliding clutchv member 34 from engagement with the clutch member 30, this movement being against the resistance of the spring 50.

. The movement of the clutch-throw lever case at 52. By pressing down on the handleV 46a of the clutch-throw lever, the pivot 49 is rocked forwardly of the line of centers of thepivots 47 and 48, lwhereupon the upperclutch member 34 will drop into engagement with -the lower. clutch member 30, such return movement being assured by the spring 50.

It will be appreciated that the clutch permits starting the motor without operating the propeller, and permits releasing the propel.

' ler and stopping its action without the necessity of stopping the motor, which is particularly advantageous when it is desired to make a number of'successive short stops on a trip, as well as when it is desired to control the propeller by intermittently discontinuing its operation when making alanding. l

Arranged beneath the clutch-throw lever is a tiller or steering lever 55,. The fulcrum for this tiller or steering lever is provided in this instance by the vertical bolt 56, the head of which supports the tiller. Said bolt is shown screwed to a boss depending from the frame member 57 which projects from the clutch case. The tiller carries at its rear end a toothed segment 58 concentric with the bolt on which the tiller is mounted. See Figs. 2 and 9. The toothed segment 58 engages a pinion 59 rigidly axed on the upper'end of the. rudder post 16. In .this instance said pinion is shown formed with an extended hub or tubular portion 60 which is rigidly secured on the rudder postand is journaled in the supporting sleeve 18 (Fig's.2 and 3). Said supporting sleeve 18 is shown formed at its upper end with a case portion 61 enclosing the pinion, said case portion being bolted'or otherwise rigidly secured to the clutch case 20. The toothed segment works in a slot in the front side of the case portion and meshesl with the pinion. The ratio of diameters of f will be at the position indicated by the line marked Neutral in Fig. 9. At this neutral position of the tiller, the toothed segment ex- 'tends more than 45 degrees to one side of its point of engagement with the pinion, and more than 90 degrees to the opposite side. Hence by swinging the tiller from its neutral position through a 45 degreeangle in either direction, the rudder and propeller may be correspondingly swung through a 90 degree angle in either direction, for steering the boat as required. Also the tiller can be swung a full 90 degrees to the right (as viewed in Fig. 9), while continuing the engagement of the toothed segment with ythe pinion, so as to completely reverse theposition of the propeller and rudder, when it is desired topropel the boat backward.

The tiller carries a springactuatedftoothed latch 62 engaging the teet of a segmental rack 63 formed on the inner edge of a curved bar 64 which is afliXed to the frame member 57. This toothed rack 63 has an extent of over 90 degrees, i. e., an extent of over 45 degrees in either direction from the line of the neutral position of the tiller. The whole arcuate extent of the curved bar 64 is substantially greater than 135 degrees. It will be apparent that this arrangement provides for swinging the tiller through an angle of 45 degrees in either direction Ifrom its neutral position for steering the boat, and securing the tiller in any desired adjusted position for steering by engagement of the latch 62 with the toothed rack 63; and when it is dpsired to reverse the position of the propeller the tiller may be swung to the right to the position marked Reverse'in Fig. 9, this position being 90gdegrees from the neutral position, and the corresponding position of the propeller being 180 degrees from its normal neutral position. When the tiller is thus brought to its reverse position indicated, there is still ample reach of the'bar 64 and ample reach of the toothed segment 58 to permit movement of the tillerin either direction through a substantial angle from the reverse position for such steerlng as ordi- \narily required when the propeller is reversed.- The specific construction shown perwere no rudder and hence the `mechanism described will function for steering purposes even though the rudder may be omitted.

The handle of the tiller extends forward suficiently beyond the handle 46 of the clutch-throwlever, so as to leave the. tiller handle unobstructed for steering, while at the same time the handle of the clutch-throw lever is conveniently located in proximity to the tiller handle so that the steersman may readily shift his hand from one handle to lthe other. .In Fig. 2, the tiller .handle is shown mounted on a tube` 66 affixed as an extension to the tiller. In the handle is a spring-pressed rod 67 extending into a longitudinal bore in the main portion of the tiller. This rod carries a transverse pin 68 which carries the latch 62. The -rod 67 is springpressed outward by the expansive action of the coil spring 69 surrounding the rod, said sprin bearing at its inner end against the. should y against the stop collar 71 aixed to the rod. Said stop collar abuts against the tubular nut 72, limiting the outward motion of the rod. The rod has on its outer end the push button 73 which may be pressed with the thumb 'to force the rod inward for releasingv the latch 62 from the toothed rack 63. In this inward movement of the rod the transverse pin 68'moves in a slotted portion 74 of the tiller. l l

It will be observed that the construction described provides for the rigid mounting of the outboard motor on the boat while the rudder post may be` rotated by the tiller for steering. In other words, the rudder 'post instead of'being rigidly connected with the motor casing as in previous constructions is rotatably fitted in reference to the mounted structure, so that the steering may be accom plished without accompanying swin 'ng of the motor itself, whichhas been an o jection to prior outboard motors. l

In yan outboard motor, water -for cooling purposes is pumped to the engine by a submerged pump driven by the propeller-operati ingshaft. As the light type of engine usually employed has only restricted spaces in its cylinder heads for circulation of cooling water, it is desirable to have fresh cold water constantly supplied to these spaces during the running of the engine. Where, as in this case, a clutch mechanism is provided for releas'ably connecting the motor to the propeller-operating shaft, with a view to disconnecting said shaft and allowing the propeller 'to bef/at rest at will while the engine is running, the problem is presented of maintaining continuous operation of lthe water pump. In the illustrative apparatus, this problem is met by associating with the propeller-operat--.

ing shaft a pump operating device vwhichmay -be continuously driven from the motor shaft.

er and bearing at its outer endv 'Phe specific means illustrated in this connection will now bedescribed;

The propeller-operating shaft fis enclosed by a tubular shaft 75 which is'em'ployed for operating the pump, as will presently be exp ained. Rigidly secured on the upper end of said tubular shaft 75 is a cross arm 76 (Figs. 3 and 4). Said cross arm 76 has u turned ends 77, which are slidably engaged bifurcated lu 78 of the slidable clutc member 34. the slidable clutch member is lifted to release'thel clutch, it maintains its engagement withI the upright ends 77 of the cross arm. The tubular shaft 75 is therefore l continuously driven from the motor Shaft through the slidable clutch` member 34 regardless of whether or not the clutch members 30 and 34 are in engagement. When the clutch members are in engagement, the ropeller-operating shaft and the surroun g pump-operating shaft will rotate together,` but when 'the clutch is released Vthe umpo erating shaft will be driven alone. suit# a le bearing designed for radial-rand axial thrust is interposed between the cross member 76 and the bottom plate of the clutch case. As shown in Fig. 3, this bearing comprises the concentric members 79 and 80 and interposed balls 81. The bearing is iitted'in a seat in `the clutch case provided by the cirplunger rod 86, the rod being driven in one direction by theeccentric and returned by a spring which is .not shown. The pump itself is or may be of a well-known type employed in `connection with outboard motors and its details are therefore not illustrated. Y

As shown in Fig. 1, a pipe 87 conducts water from the pump. This pipe connects through the casing 88 with a conduit 89 in the rudder post. As shown in-Fig. 2, the conduit 89v in therudder post connects with a pipe 90. Said pipe 90 is'shown in Fig. 1 and connects at the T .91 with two pipes, lone of which is indicated at 92, respectively leading to the water jacket spaces in the cylinder heads. The inlet connections for the cooling water are indicated. at 93 in Fig. 3. Outlet connect1ons are indicated at 94, these being in coln-4 munication through piping 95`with the water dischargev pipe 96. Q

Referring to the conduit` 89 in the rudder post, a special construction of the post to provlde such conduit is shown-in Figs. 7 and formed to' provide the troug like part 97,

As shown ythe post is lon tudinally dewhich corresponds substantially to that of tlietubularipost, is welded to the post over thefdeformedportion. In this cover plate arethe inlet and outlet openings 99 and 100,

the"A inlet 99 being in connection through the casingl 88v with'the pipe leading from the water 'pump' `(Fig. la), and the outlet 100 being in communication through the sleeve 18 with the pipe 90 (Fig. 2'). Y

As shown in Fig. 2, the supporting sleeve 18 contains the gland 101 which compresses the packing 102 so as to prevent the water passmg up to the pinion 59. Below the water outlet 100 and pipe 90 are the ackings 103 and 104 compressed by the tubu ar gland members 105 and 106. A latch for the last mentioned member is indicated at 107.
